Fast analog output performance measurements
All measurements of this section were performed with the same measurement set-up as described in the analog
outputs performance section above.
Spectral noise
The noise spectrum of the fast analog output is measured with the output connected to a battery-powered Stanford
Research Systems SR560 low-noise differential preamplifier set to gain 1000, and the spectrum is recorded using a
National Instruments 4071
PXI digital multimeter operated in digitizer mode, or a Nanonis OC4 (1.25 MHz
spectrum). The pictures below show the noise spectrum for the range of 1 kHz (0 V output), as well as for the
frequency range up to 1.25 MHz and below 50 Hz.
